Class
	Foam::rotatedBoxToFace

Description
	A topoSetSource to select faces based on face centres inside
	rotated/skewed box (parallelopiped?).

	Box defined as origin and i,j,k vectors.
	E.g. box rotated 45 degrees around z-axis with sizes sqrt(0.2^2+0.2^2)
	(and extra large, 200 in z direction):
	@verbatim
	   origin   ( 0.4 0.4 -100);
	   i        ( 0.2 0.2    0);
	   j        (-0.2 0.2    0);
	   k        ( 0.0 0.0  100);
	@endverbatim
